Today's award goes to an over-enthusiastic and under-trained policeman in Pakistan.
A hand grenade exploded inside courtroom in Karachi’s Anti-Terrorism Court (ATC) after a judge asked a police constable if he knew how grenades worked.
The constable, instead of explaining his expertise in weapons and grenade handling to the judge, opted to demonstrate practically by promptly pulling out the pin from the grenade.
This resulted in a loud explosion, injuring five including the judge, the constable and a court clerk.
. . .
It is safe to say that now the whole court knows how grenades work, including the curious judge.
According to authorities, the constable who apparently knows how grenades work will be punished severely after he recovers from his injuries.

Sounds like a triumph of optimism and enthusiasm over (in)experience! A tip o' the hat to reader M. J. for sending me the link.
